Chandra and NuSTAR follow-up observations of Swift-BAT selected AGN
Stefano Marchesi, Luke Tremblay, Marco Ajello +5
Based on current models of the Cosmic X-ray Background (CXB), heavily obscured Active Galactic Nuclei (AGN) are expected to make up ~10% of the peak emission of the CXB and ~20% of…
Constraining the Physical State of the Hot Gas Halos in NGC 4649 and NGC 5846
Alessandro Paggi, Dong-Woo Kim, Craig Anderson +15
We present results of a joint \textit{Chandra}/\textit{XMM-Newton} analysis of the early-type galaxies NGC 4649 and NGC 5846 aimed at investigating differences between mass profile…
Disturbed Fossil Group Galaxy NGC 1132
Dong-Woo Kim, Craig Anderson, Doug Burke +10
We have analyzed the Chandra archival data of NGC 1132, a well-known fossil group, i.e. a system expected to be old and relaxed long after the giant elliptical galaxy assembly. Ins…
Discovery of Kiloparsec Extended Hard X-ray Continuum and Fe K alpha from the Compton Thick AGN ESO428-G014
G. Fabbiano, M. Elvis, A. Paggi +5
We report the discovery of kpc-scale diffuse emission in both the hard continuum (3-6 keV) and in the Fe K alpha line in the Compton Thick (CT) Seyfert galaxy ESO428-G014. This ext…
X-ray emission from the nuclear region of Arp 220
Alessandro Paggi, Giuseppina Fabbiano, Guido Risaliti +6
We present an imaging and spectral analysis of the nuclear region of the ULIRG merger Arp 220, using deep \textit{Chandra}-ACIS observations summing up to \(\sim 300\mbox{ ks}\). N…
The Infall of the Virgo Elliptical Galaxy M60 toward M87 and the Gaseous Structures Produced by Kelvin-Helmholtz Instabilities
R. A. Wood, C. Jones, M. E. Machacek +6
We present Chandra observations of hot gas structures, characteristic of gas stripping during infall, in the Virgo cluster elliptical galaxy M60 (NGC4649) located Mpc east of M…
